3Cleaning the CMOS sensorN

The image sensor is like the film in a film camera. If any dust or other foreign matter adheres to the image sensor, it may show up as a dark speck in the images. To avoid this, follow the procedure below to clean the image sensor. Note that the image sensor is a very delicate component. If possible, you should have it cleaned by a Canon Service Center.

While you clean the image sensor, the camera must be turned on. Using the AC Adapter Kit ACK-E2 (optional, see page 154) is recommended. If you use a battery, make sure the battery level is sufficient. Before cleaning the sensor, detach the lens from the camera.
